Class API¶

class RulerCtrl(wx.Panel)¶

RulerCtrl implements a ruler window that can be placed on top, bottom, left or right to any wxPython widget. It is somewhat similar to the rulers you can find in text editors software, though not so powerful.

Methods¶

__init__(self, parent, id=-1, pos=wx.DefaultPosition, size=wx.DefaultSize, style=wx.STATIC_BORDER, orient=wx.HORIZONTAL)¶

Default class constructor.

Parameters:

parent – parent window. Must not be None;
id – window identifier. A value of -1 indicates a default value;
pos – the control position. A value of (-1, -1) indicates a default position, chosen by either the windowing system or wxPython, depending on platform;
size – the control size. A value of (-1, -1) indicates a default size, chosen by either the windowing system or wxPython, depending on platform;
style – the window style;
orient – sets the orientation of the RulerCtrl, and can be either wx.HORIZONTAL of wx.VERTICAL.

AddIndicator(self, id, value)¶

Adds an indicator to RulerCtrl. You should pass a unique id and a starting value for the indicator.

Parameters:	id – the indicator identifier; value – the indicator initial value.

CheckStyle(self)¶: Adjust the RulerCtrl style accordingly to borders, units, etc...

Draw(self, dc)¶

Actually draws the whole RulerCtrl.

Parameters:	dc – an instance of `wx.DC`.

DrawOnParent(self, indicator)¶

Actually draws the thin line over the drawing parent window.

Parameters:	indicator – the current indicator, an instance of `Indicator`.

Note

This method is currently not available on wxMac as it uses ScreenDC.

FindLinearTickSizes(self, UPP)¶: Used internally.

GetBounds(self)¶: Returns the RulerCtrl bounds (its client rectangle).

GetDrawingParent(self)¶: Returns the window to which RulerCtrl draws a thin line over.

GetFormat(self)¶: Returns the format used to display values in RulerCtrl.

See also

RulerCtrl.SetFormat for a list of possible formats.

GetIndicator(self, mousePos)¶

Returns the indicator located at the mouse position mousePos (if any).

Parameters:	mousePos – the mouse position, an instance of `wx.Point`.

GetTimeFormat(self)¶: Returns the time format.

Invalidate(self)¶: Invalidates the ticks calculations.

LabelMajor(self, label=True)¶

Sets whether the major ticks should be labeled or not.

Parameters:	label – `True` to label major ticks, `False` otherwise.

LabelMinor(self, label=True)¶

Sets whether the minor ticks should be labeled or not.

Parameters:	label – `True` to label minor ticks, `False` otherwise.

LabelString(self, d, major=None)¶: Used internally.

OfflimitsPixels(self, start, end)¶: Used internally.

OnEraseBackground(self, event)¶

Handles the wx.EVT_ERASE_BACKGROUND event for RulerCtrl.

Parameters:	event – a `EraseEvent` event to be processed.

Note

This method is intentionally empty to reduce flicker.

OnMouseEvents(self, event)¶

Handles the wx.EVT_MOUSE_EVENTS event for RulerCtrl.

Parameters:	event – a `MouseEvent` event to be processed.

OnPaint(self, event)¶

Handles the wx.EVT_PAINT event for RulerCtrl.
